Ambient noise generated by human activity such as travel and machinery dropped by 50% last year, researchers find - "The weeks during lockdown were the quietest period we have on record," said seismologist John Clinton, referring to data archives covering the last 20 years. -
Lower background noise during lockdowns also means small earthquakes that otherwise would not be observed have been detected in some places.
Meteorologist Cliff Mass: Without global warming, we “still would have experienced the most severe heat wave of the past century.” ... Mass concluded climate change didn’t play a central role in an event largely caused by the natural variability of our regional weather. He notes the temperature soared by more than 40 degrees above the normal high, and climate change added only a few degrees, thus “a record-breaking unique heat wave” would have occurred even without global warming. In his blog, he lays out a golden rule that — based on this analysis — the bigger the temperature surge in an extreme event, the smaller the role of climate change, and accuses the World Weather Attribution report of “misinforming millions.” Mass says his criticism is grounded in a deep knowledge of the intricate mix of ocean, mountains and atmospheric flows that help to produce Northwest weather, as well as climate models he runs. ...
“I don’t believe we are facing any kind of existential threat,” Mass said. “But it is not a good idea to muck around with the climate of the planet.”
